Hey buddy here is ur answer !!!!!!
→ If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction(angle between the ray in the medium and the normal) .
hope u like the answer !!!
plz mark it as brainalist one
